Manufacturing Locations

Home to Traction Drives, the Georgia 400 (GA400) facility in Alpharetta, Georgia manufactures complete propulsion solutions for the North American rail market. Products are both innovative and well-proven – providing the highest degree of reliability but with minimum maintenance costs. The product portfolio includes Converters, Motors, Gearboxes and Auxiliary Power Supplies. Products are project-specific designed, ensuring proper adherence to customer requirements.


In operation since 1990, with a manufacturing space of 138,000 square feet, the GA400 facility can manufacture both standard and custom products. The factory is ISO certified and can manufacture to standards like UL, CUL, CSA, as well as manufacture Buy America compliant products. The core competencies of the factory include manufacturing and assembly, testing, wire kits & harness production, and service and repair, with a strong adoption of a Siemens Production System (SPS).

The Rail Automation, Louisville, Ky., facility houses the global headquarters of the Siemens Freight and Products Business Unit, which manufactures rail signaling and communications products, such as grade crossing warning lights, bells and gates, for rail lines around the world. The manufacturing facility assembles and wires the complex control equipment required for train control systems, wayside signal systems and grade crossing warning systems. Siemens also engineers software solutions at this location such as Positive Train Control (PTC), a signal enforcement system that will lead to more efficient train control, specifically for the North American market. Siemens finalized its acquisition of Invensys Rail in May 2013, expanding the company’s footprint in the global rail automation market and strengthening its technology offerings, including PTC solutions. This facility houses engineering, manufacturing and assembly, sales, marketing and program management personnel. Siemens employs a total of 300 people at the plant.

Rail Automation currently employs roughly 200 workers at its Marion, Ky, plant. The facility was opened in 2001 and began relay production. Since the facility opened its doors, additional operations were added, opening the box assembly and welding functions to support cross cantilevers.


From 2005 to 2008, wayside wiring was added for Norfolk Southern Railroad and other initiatives added signal mast wiring and machine shop activates. In 2009, after the purchase of Quantum Engineering the plant underwent a upgrade to facilitate the expansion.


From 2010 to 2013, manufacturing operations continued to grow and additional product lines were added, driving another 26,000 square foot addition to the facility. In 2015, the Marion facility expanded again, by moving the manufacturing portion of our traffic controller operation from Austin, Texas, to Marion.

This 60,000 square-foot plant is dedicated to our growing rail service, maintenance, and repair operations and serves as Siemens Mobility Rail Services U.S. headquarters and West Coast service hub. The new facility is providing work for more than 100 employees and plans to continue hiring to support its growing service business. Shortly after opening, McClellan Park took on the modernization of thirty-two SD160 light rail vehicles for Calgary Transit in Alberta, Canada. This modern rail service facility complements our existing rail manufacturing operations in nearby South Sacramento.

The Locomotive Service facility combines Siemens’ global digital analytics know-how with its extensive industry knowledge to move rail further into the digital age. Using the latest in digital and predictive technology, the New Castle team will train service technicians and remotely maintain Siemens locomotives. The facility serves as the company’s digital service, supply chain distribution center, and technical field training hub in the region.


The data from more than 800 data points on the locomotives, pulled in real time, can help diagnose fleet issues and develop predictive maintenance capabilities so issues can be identified before they become a problem. The Siemens team is already putting its data capabilities to use by working with Amtrak to monitor and analyze data from Siemens-built ACS-64 locomotives running along the Northeast Corridor.

Rail Automation manufactures and engineers all of their Cab Signaling and Positive Train Control equipment in Pittsburgh, Pa. In the fall of 2014, Siemens relocated this manufacturing facility from East Pittsburgh to Munhall, Pa. The modern waterfront development space now combines our engineering office as well as our manufacturing floor. The facility is 23,000 square feet and houses state-of-the-art business equipment. There are currently 240 employees who work in our Pittsburgh facility.


This facility is known for making all of the onboarding equipment, which includes Cab Signal systems, display units, controls, control boxes, pickup receiver bars and axel generators.

Rail Electrification in Tualatin, Oregon, specializes in the design, systems integration, assembly, testing and commissioning of traction power substations, and provides overhead catenary assemblies for installation. Rail Electrification employs 70 experienced professionals, engineers, technicians and skilled workers.


The combined facility and office currently features 24,000 square feet of total constructed area divided into DC switchgear assembly, rectifier assembly, warehouse, overhead catenary assembly, and engineering and office space. Design, engineering, procurement, fabrication and assembly, as well as bid-related activities take place in this facility.

Our Sacramento, Calif. plant serves as the North American Rail Manufacturing Hub and Headquarters for Rolling Stock. The rail plant boasts full manufacturing capabilities, including design, engineering, testing, carshell, bogies, subassembly and final assembly. With all aspects of the manufacturing process taking place at one facility, Siemens Mobility offers customers unparalleled access, optimum project management and quality, from start to finish right here in California.


Siemens Mobility has been manufacturing in Sacramento for more than 30 years. The rail plant in Sacramento is an example of environmentally friendly manufacturing, using a 2MW solar installation which powers more than 80% of our facility.


Since opening the doors for business in the Sacramento community, the manufacturing portfolio has expanded from building light rail vehicles, to manufacturing advanced technology passenger rail locomotives and trainsets, as well as streetcars for more than 30 transit agencies in the U.S. and Canada, with more than 2,700 vehicles being manufactured at our Sacramento rail plant.


Currently, more than 1,500 people are employed at the 583,000-square-foot facility, on 60 acres of land in Sacramento. As the operation in Sacramento continues to grow, Siemens has the flexibility to produce a wider array of products to respond to America’s rail renaissance.
